Abstract: A decoder implemented using bifet technology to exhibit high performance, high density, and low power dissipation. The decoder has multiple input lines for conducting signals at ECL-compatible voltage levels and an output line for conducting signals at CMOS-compatible voltage levels. The output line is enabled in response to a predetermined combination of ECL-compatible voltage level signals on said input lines. The decoder comprises a gate for generating an OR output at ECL-compatible voltage levels according to the input line signals. An inverter is coupled to the OR gate for inverting and amplifying the OR output to produce an inverted output at CMOS voltage levels. A word line driver is coupled to an output of the inverter for isolating and driving the output line according to the inverted output. Finally, power saving means are coupled to the inverter for minimizing power dissipation in the decoder.

Abstract: When a lid (5) of a reagent container housing unit (7) is closed, an opening/closing detector (4) outputs a signal. A control unit (11) gives an instruction of moving a row of reagent containers (1) and a bar code reader (3) relative to each other to a driving unit and an instruction of starting the data reading operation to the bar code reader (3). When the lid (5) of the container housing unit is closed, all the data which have been already read are reset. An automatic analyzing apparatus can select, in place of the data reading mode, the liquid level detection mode in which a level of the liquid in each of the reagent containers is detected.

Abstract: For use with marine seismic streamers (22), a two-wire, multi-channel communication system capable of handling the high throughput necessary for effective communication between a central controller (38) aboard a tow vessel (20) and the many sensors (24,26,28) deployed along the streamer (22). The central controller (38) includes an intelligent modem with the capability of transmitting and receiving frequency-modulated message signals on one or more signal lines, such as conventional twisted-pair wires, over a number of individual inbound and outbound frequency channels. In the preferred embodiment, seventeen channels are spread over a frequency band ranging from about 20kHz to 100kHz, thereby making available for communication a bandwidth much wider than available in conventional single-channel streamer communication. In this way, many positioning sensors, such as compasses, depth sensors (24), cable-leveling birds (26), and acoustic-ranging transceivers (28), attached to the streamer (22) and each having a transmitter and receiver tuned to one of the modem's inbound and outbound channels, respectively, can be put in communication with the modem. To take advantage of its high throughput capability, the intelligent modem refers to a stored table of individual sensor parameters, such as sensor type, transmit channel, and receive channel, to schedule an efficient scan of the sensors. As a diagnostic tool, the communication system also monitors the quality and performance of the communication link by measuring and recording such parameters as the transmitted and received signal strengths, signal-to-noise ratios, and number of incorrectly received messages.

Abstract: The invention relates to a device for the long-term leak monitoring of double-walled container systems, in particular double-walled tank bottoms, which permits, at low cost, the monitoring of, if appropriate, a multiplicity of double-walled tank bottoms cyclically or simultaneously with respect to the occurrence of leaks. By means of the device it can be established whether a leak has occurred in the outer bottom or in the intermediate bottom, the size of the leak and the location of the leak being able to be determined. According to the invention, an intermediate layer is applied to the inside of an outer bottom, the said intermediate layer serving to support the inner bottom. A sensor cable having a variable dielectric constant is laid in the intermediate layer, protected to a large extent. By means of the special intermediate layer, it is firstly possible to dissipate the forces acting on the tank bottoms and, besides, to lay the sensor cable at defined locations which are known in detail. In order to make possible a prescribed propagation of liquid, the intermediate layers have special recesses or are laid in such a manner that the liquid flow is not impeded. <IMAGE>
